Right-to-farm and fence law shape rural life in Clark County Clark County is agricultural, so right-to-farm protections and Missouri's fence law are practical issues for anyone buying rural land or living next to a working farm. Three rivers meet the land in Clark County Clark County's eastern and northern edges follow the Mississippi and Des Moines rivers, with the Fox River inland, so flood-zone status is a real factor for buyers and varies parcel by parcel. Wells and septic systems for rural Clark County property Much of Clark County is rural, so many homes rely on private wells and on-site septic rather than municipal water and sewer, which changes what a buyer needs to check.
